I believe you are referring to the notches in the drawer back at the bottom corners to allow the blum motion glides to pass through. I usually use a dado blade.
Yep thanks. That would be four passes and two fence settings per drawer to get the 1 3/8” notch for the Blum slide.
Stack the backs and dado them before assembly to make quick work.
Willemjm you dont, here is the EZ,bestest way, on the back pc rip them right at the top of the dado. This then allows you to assembler the drawer, then SLIDE THE BOTTOM INTO IT, CUT TO LENGTH, WHICH you can measure b4. that way you can solidly staple the bottom pc onto the back. If that is as clear as mud, either PM or call me 973 945 6686
Understand completely, I am not worthy of dovetails , therefore I don't run into that problem. Yes I tried, failed many times, gave up. I truly think it is because I do not use solid stock for drawers. Everything I do except for face frames, doors,fronts etc is pre finished ply. dovetails don't seem to take kindly to plywood.Wabbits and glue and staples
When I did that big notch, I used the protractor head that come with machine, screwed a pc of ply to it,and made a jig to use with a dado blade. I took the dimension to the left side of that notch, setup my fence for it, then made a block that would be positioned between the fence and the piece for the right side of the notch, then just nibbled out the middle. by having that ply, it was a way to solidly hold the part, you could make it tall enuf to clamp to.:gar-Bi
I cut mine on a shaper with a 1 1/2 straight cutter after drawers are put together. Raise the cutter up to miss the drawer side and set the fence to the depth to the drawer bottom. Then run all your drawers through on one side. Then you will have to take the cutter off And turn it over, reverse the shaper and do the other side of all your drawers. There is a good video of a guy doing drawers this way on YouTube. Just search for drawer notches on shaper. This is the fastest and cleanest way I have been able to do the notches.
